Select the most appropriate option to fill in the blank.
A note of ______ during the leaders' meeting at the UN.

Correct option is B

The correct option to fill in the blank is (b) discord surfaced.
Explanation:
· The sentence describes a situation at a high-level meeting (UN), suggesting disagreement or lack of harmony among leaders.
· “ Discord” fits contextually and grammatically: it refers to conflict or disagreement.
Example:
· A note of discord surfaced during the negotiation talks.
Meanings of other options:
· (a) friction surfaced – Friction = tension (but "friction" is less formal and doesn't fit as naturally in the sentence) (तनाव)
· (c) grievance surfaced – grievance = complaint (शिकायत), which would need a more specific context
· (d) strife surfaced – strife = violent conflict (संघर्ष), too strong a word for this context
